You’re sitting on the train home and the person opposite you yawns(打哈欠). Suddenly, you’re yawning with him, though you’re not tired.

   This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans. Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious(有感染力的) yawning, which showed that humans communicate regularly with out words.

   Hugo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness and sadness can spread like the common cold. According to Critechley, our mind and body are in constant exchange about how we’re feeling. “Emotions are closely linked with states of internal(内部的) responses,” he explained. “ There are also more visible changes in our gestures and facial expression. When we’re in a group, these signals can spread to another person. For example, there’s the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a change in our heart rate and blood pressure.

Hugo Critchley further explained, “Our bodies synchronies and when we like the other person, we ever copy his behavior. Next time you chat with a friend, take note fo how you’re sitting― it’s pretty likely that you will be the same. Scientists believe it’s our way of telling each other that we’re partners. Through body language, humans give each other very subtle(微妙的) but clear signals that show emotions.”

So, what lessons can we learn from this? “ Spend time with happy people― otherwise your health could suffer,” said Critchley.” When we’re sad, our body goes into fight or flight mode. But when we’re happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us.”

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
Fifty years ago, nature study was not part of school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.
For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody's daily life. To know about the water table (水位) in ground is just as important to us as a knowledge of the basic math formulas(公式). We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man's fellow creatures on this planet is figured not only in square measure of surface but also in cubic（立方体的） volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.

One night recently, I was driving down a highway at about 60 miles an hour. A car came from the _21_ direction at about the same speed. As we _22_ each other, I looked into the driver’s eyes for a second. I  23  whether he might be thinking, as I was, how  24  we were on each other at that moment. I was relying on him not to fall  25  , not to cross over into my lane (车道) and bring my  26  to a sudden end. He relied on me in just the same way without doubt.
I believe that is the way the world _27 . At some level, we all depend upon one another. Sometimes that dependence requires us simply not to cross over the double yellow line. Sometimes it requires us to _28  cooperatively, with friends or even  29 .
_30 technology makes our world smaller, the need increases for cooperation. In 2003, doctors in five nations were encouraged to find the causes of SARS, saving thousands of lives. The  31 of international terrorism has shown itself to be a similar problem, one requiring the            32  across the world. We must  33  that our future is not controlled by ourselves alone.
I’ve come to believe that one must rely upon the good faith and judgment of others. So, while  34  alone down a dark road, we must know the coming light may not be a danger, but a         35  moment of trust.

I believe that families are not only blood relatives, but sometimes people who show up and love you when no one else will.
In May 1977, I was living in a Howard Johnson’s motel off Interstate 10 in Houston. My dad and I  41  a room with two double beds and a bathroom was too  42  for a 15-year-old girl and her father. Dad’s second marriage was   43  and my stepmother had   44  us both out of the house the previous week. Dad had no  45_  what to do with me. And that’s when my other family   46 .
Barbara and Roland Beach took me into their home   47  their only daughter, Su, my best friend, asked them to. I   48   with them for the next seven years.
Barb washed my skirts the same as Su’s. She   49  I had lunch money, doctors’ appointments, help with homework and nightly hugs. Barbara and Roland attended every football game where Su and I were being cheerleaders.  50 I could tell, for the Beaches there was no  51 between Su and me; I was their daughter, too.
When Su and I 52 college they kept my room the same for the entire four years I attended school. Recently, Barb presented me with an insurance policy they bought when I first moved in with them and had continued to pay on for 23 years.
The Beaches knew  53 about me when they took me in – they had heard the whole story from Su. When I was seven, my mother died and from then on my father relied on other people to _54 his kids. Before I went to live with the Beaches I had believed that life was entirely   55__ and that love was shaky and untrustworthy. I had believed that the only person who would take care of me was me.
 56 the Beaches, I would have become a bitter, cynical (愤世嫉俗的) woman. They gave me a(n)  57 that allowed me to grow and change. They kept me from being paralyzed by my _58  , and they gave me the confidence to open my heart.
I   59  family. For me, it wasn’t the family that was there on the day I was  60 , but the one that was there for me when I was living in a Howard Johnson’s on Interstate 10.
